<p>Find python interpreter</p>
<p>This module finds if Python interpreter is installed and determines
where the executables are.  This code sets the following variables:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>PYTHONINTERP_FOUND         - Was the Python executable found
PYTHON_EXECUTABLE          - path to the Python interpreter
</pre></div>
</div>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>PYTHON_VERSION_STRING      - Python version found e.g. 2.5.2
PYTHON_VERSION_MAJOR       - Python major version found e.g. 2
PYTHON_VERSION_MINOR       - Python minor version found e.g. 5
PYTHON_VERSION_PATCH       - Python patch version found e.g. 2
</pre></div>
</div>
<p>The Python_ADDITIONAL_VERSIONS variable can be used to specify a list
of version numbers that should be taken into account when searching
for Python.  You need to set this variable before calling
find_package(PythonInterp).</p>
<p>If calling both <code class="docutils literal notranslate"><span class="pre">find_package(PythonInterp)</span></code> and
<code class="docutils literal notranslate"><span class="pre">find_package(PythonLibs)</span></code>, call <code class="docutils literal notranslate"><span class="pre">find_package(PythonInterp)</span></code> first to
get the currently active Python version by default with a consistent version
of PYTHON_LIBRARIES.</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>A call to <code class="docutils literal notranslate"><span class="pre">find_package(PythonInterp</span> <span class="pre">${V})</span></code> for python version <code class="docutils literal notranslate"><span class="pre">V</span></code>
may find a <code class="docutils literal notranslate"><span class="pre">python</span></code> executable with no version suffix.  In this case
no attempt is made to avoid python executables from other versions.
